Mystery solved!! I got sold some mil surp 54R by mistake and I didn't catch it.

Ok. So my AK-47 has stumped me once again. The chamber looked way to small for a 7.62 and I happened to have some 5.45 sitting in a box in the basement. So, I decided to check the muzzle end and it would only go in a little. So I turn the barrel around and tried the other end. It wouldn't go in passed the shelf I think it's called? The widest part of the taper on the case. Also, the bolt is way to small for the 5.45. All I can think of is this AK got re-chambered?

Any ideas?

I'm gonna try to find a smith somewhere. I live in the boonies so it's not going to be easy.

Unless you know for certain what you have the only safe option is to have a gunsmith cast the chamber and determine the caliber. What caliber is it supposed to be, have you ever shot the rifle, is it a .22lr AK clone? really no way anyone can answer any questions. Can you post a pic of the complete rifle, is it an AK 47 or and AK 74?

It's currently disassembled. I have never fired it before. The barrel trunnion is marked M70AB2 1988. Also marked I believe a serial number 446022. There is a letter Z randomly marked near the model number as well. I was told that it was a Yugo Underfolder.
